Hi ppl,

   I have a stupid (newbish) question about table read using TBLPTRU,
TBLPTRH, and TBLPTRL. I understand what they do and how to use them.

The question is: if I need to read the table in the interrupt, is it a good
idea for me to store the original values of TBLPTRs or should I disable
interrupts when I need to do program flash memory reads/write in the main
loop (like a critical section in x86)?

Also, shouldn't this problem also apply to FSRnH / FSRnL? How come the
manual doesn't mention this at all?

In the example in the PIC18 Reference, the manual only mention to save
WREG/STATUS/BSR...
